Deer Fly eggs
They are in the family Tabanidae, genus Chrysops but other than that I don’t know the species of these. I did happen to see a fly laying eggs but by the time I moved closer and focused my camera it had flown, leaving this very white mass of freshly laid eggs. They lay the eggs in tiers which contain a few to several hundred eggs. The eggs are cylinders measuring from 1 to 2.5 mm long. Their choice location is on vegetation which hangs over water so I was in a prime spot along this lake where the vegetation is not too dense. The eggs first appear white as in this photo and later turn brown as in the first photo and then almost black as in the last photo. I thought myself lucky to have found all three stages in the same area.
After about 4-5 days the eggs hatch and the larvae drop down and burrow into the soil. They will overwinter and mature in late spring.
In the past when I walked through the woods I would see stuff like this and keep going. Now I have learned to stop and really look at new, odd and strange things and I have found them quite intersting. It gives me more of a connection and appreciation for the lives of other creatures on our planet.
